Nice pics over there, enough to keep you busy a while even with the grapple.Awesome!!!!! Very handy attachment.
The neighbor built on similar for the skid steer this past fall. He found a smaller grapple on auction time.

Works really slick and we have a pretty good system down now of me cutting a log load while held in the grapple. After he lets the last cut go he goes back to the log yard for another load and repeat/rinse. His turn around times are about 5 +/- minutes.
